Be it known that I, ERNEsr WILLI/nu Comm, n.citi.

zen ofthe United Statesof America, residing at New York city,in the countyof New York and State of -New York, have invented new and useful Improvements in Dehydrating Apparatus, oiwhich the following is af specification. L

. My invention relates dehydrating apparatusfland air tight stop. I The distance between a ef adjacent is especially designedfor the ,treatment of food products,',hoth animal. and vegetablefwhereby they -are thoroughly dehydrated, while at tlie'same i.;iiuef nonin-l4 taining their'cellulr structure and-chemical'eomposition unimpliiiryed sothat theycan b e perfectly'restored to their originalfundehydrated condition by simple a-more 4or less fnelydiyided-state, into contact first,

' with air which has already passed through previous portions of the saine" or other material, whereby-it already absorbed s ome moisture and become somewhat cooled; and gradually subject said material tothe ac` tion of air which isprogressiyely more and more dry and l of ahigher. temperature until finally itcomes in contact with air of. the initial dryness and temperature. lIt is also `necessary in the treatment of some delicate substances, to provide means to retard the egress ofthe air from the apparatus, whereby a certain pressure 'isset up, which ca part of theniaterial-being treated, prevents any injury 'to the cellular structureA thereof and thoroughly dlehy- "les f an'tomaticvwill "bereferred to in the detailed description whichffollows, reference bein'gmad'to the acczompa'n'yl-f the same.

My improved apparatus comprises in general a. de#
